Facing heat from the media over its inaction,police today arrested four advocates in connection with the attack on media personnel by a section of lawyers during the mayhem that rocked the city civil court on Friday.

The arrests came after the media rejected the judicial probe ordered into the attack as an eyewash and demanded that the guilty advocates be immediately brought to book.

Mirji said 31 cases of rioting and assault had been registered in connection with the unprovoked attack on the journalists,OB vans and the police that left at least 20 persons injured and evoked widespread condemnation.

Police also registered a complaint of assault and robbery filed by the driver of Karnataka High Court Judge K L Manjunath. The complainant,M S Jagadeeshaiah,said some advocates beat him when he came to the court complex to drop the judge and robbed him of a gold chain and a cash of Rs 1,900.

Courts here remained closed today while prohibitory orders were in force around city civil court complex,which witnessed violence when lawyers created ruckus before turning violent protesting presence of mediapersons to cover the appearance of former minister and mining baron Janardhan Reddy in the CBI court in connection with an illegal mining case.
